Abstract (en)
The present invention relates to a quantum random pulse generator having enhanced security using a phenomenon in which a radioactive isotope naturally collapses. The quantum random pulse generator includes a photodiode detection unit which has a photodiode disposed at the center of the photodiode detection unit on a top surface, a radioactive isotope emission unit which emits alpha particles discharged when an atomic nucleus naturally collapses toward a photodiode, and a plate which is disposed on a top surface of the radioactive isotope emission unit and supports the radioactive isotope emission unit. The alpha particles discharged by the emission unit come into contact with the photodiode to generate a random pulse.
